Abstract

Provided are a method and device for manufacturing shot particles with improved yield. In a molten droplet forming space (5) which is covered by a cover (3), which covers the water surface (1) in a water tank (20) and the periphery of a rotating centrifugal disk (2) that is disposed above the water surface, and a tundish (4) which is provided so as to pass through the cover, gas is discharged from an opening part (6) in the molten droplet forming space, and a water film (9) is formed on the inside surface of the cover. Molten metal (10) flows out from a hole part (11) in the bottom of the tundish and is supplied on to the rotating centrifugal disk, and molten droplets are formed from the molten metal supplied to the centrifugal disk due to centrifugal force. Thereafter, the molten droplets are collided against the water film on the inside of the cover and shattered into droplets smaller than the molten droplets, after which the small droplets are cooled and solidified.
